I was getting Free to wrong pool last year when I attempted to use the
Windows Fork with Tk being used in the child process. The details of my problem set were different than yours but perhaps the overall problem set and solution approach could be similar. After some digging, the problem turned out that Tk was not thread safe. My answer was to use the fork earlier on in the program, and not "use Tk" in any module prior to the module that used the fork. The parent does some things and waits a prescribed time for the child to finish just as before, only instead of the child pop up any error message, which is what used Tk, the child now writes any reports to a temp file (that is known to the parent). After the child exits - or is killed by the parent - the parent then returns the file contents to the caller, and a subsequent module handles using Tk to pop up any error messages. One more thing. If you decide to use the Windows fork, do not use the sleep command in the parent or child. It hangs. Instead, use select(undef, undef, undef,whatever); In reply to Re^4: LWP, DBI and Free to Wrong Pool error
